, 1 Claim.

, The present invention relates to a proportional recording andindicating instrument and constitutes an improvement of the instrumentshown in my co-pending application, Serial No. 368,696, filed December5, 1940. The instrument is adapted to be used to record and indicatedata.

and information of any subject matter and is particularly useful inrecording production, allocation of raw materials, transfer ofcommodities, monetary values, machines and equipment, etc. and any itemsin general.

It is an object of the invention to provide the instrument of myco-pending application with a proportioning gauge in order tographically record and indicate any items utilizing the vertical andhorizontal distances as coordinates of the items set up in theinstrument. The recorded line is projected at an angle to the verticalto permit a greater proportion of items to be indicated graphically andvisually. A further object of the invention i to combine a counter withthe instrument whereby the actual number of items may be ascertained ata glance.

A still further object of the invention is to render it possible to setthe instrument for a certain proportion so that the resulting linerecorded on a record sheet can be visually observed as to the itemswhich areto be counted by taking due note-of the vertical distancerepresented by the lateral or angular distance of extent of theprojected line.

The instrument of Figs. 1 to-5 embodies certain features which aredescribed and illustrated in my said co-pending application. As shown insaid application and as illustrated herein, a base plate i5 is providedwith two uprights l6 and 11, one at each end thereof, in which a spiralgrooved or threaded actuating rod I8 is rotatably mounted. A pair ofsolenoids l 9 and 20 impart a quarter turn in'counter orcounterclockwise direction on line to the rod l8 by means of ratchetmechanism,

Fig. 3, shown and described in said application. Each end of the baseplate is provided with a pair of spring pressed pins 2| by means ofwhich the instrument may be secured on a board or other support. Thelongitudinal guide track or rail 22 is suitably grooved to accommodate apair of magnet bars or slugs 23 and 24 to each of which a pointer 25 and26 respectively is secured. A second rail or track 21 is secured to theuprights l6 and I! to receive the silver tapes or ribbons 28 and 29,each having an adjusting knob 30 and 3| to adjust the end edge 32 and 33relative to a double contact strip 34 and 35.

The spiral grooved actuatin rod l8 has a guide nut 36 threaded similarlyto the rod so that upon rotation of the rod the nut will be movedlongitudinally of the machine. The double contact strip 34 and issecured to the nut 35 by means of an arm 31, Fig, 4, and a main arm 38is secured to the nut having a depending actuating pin 39 for thepointers 25 and 2B 'and a marking or line drawing device or tylus 40such as an ink retainin fountain. The fountain 40 is preferably in theshape of a cone having an upper opening and a bottom capillary portthrough which the ink flows to a record sheet or graph paper. Any othersuitable inking or line drawing device may,

of course, be used. a

One end of the rod l8 has an extended portion 4| on which the spacedratchet teeth 42, Fig. 3, are provided aswell as a knurled knob 43 and abevel gear44, Fig. 1; The knob 43 is for the puroperated by a shaft 41having a bevel gear 48, the- 7 latter being adapted to mesh with thegear 44. Two knurled knobs 49 and 50 are provided on the shaft 41 ofwhich knob 49 is for the purpose of clearing the counter, that is set itto zero, and knob 50 will set or advance the counter wheels numericallyto any desired number.

As shown in Fig. 3, counter 45 is slidably mounted on the extension 46by means of lugs 5| having 7 slots 52 therein and limited by suitablemeans such as screw bolts. A spring 53 bearing against an uprightportion 54 on the extension 46 forces ferred to as an indicating andrecording instrument 5! is used in combination with the counter 45 and aproportioning gauge 58.

The proportioning gauge 58 is composedof twoparts, a scale portion 59in-the form of a part circular plate, and pointer or setting indicator60 secured to the base plate 15. The scale portion 59 is provided witha' series of peripheral teeth 6|, scale graduations 62, a plurality ofperforations 33 and a center perforation into which a pivot screw 84 isadapted to project. The screw GE is threaded into the base plate and thelatter is cut out on the bottom side to accommodate the gauge 58, Fig.4. The perforations 63 are adapted to receive pins to secure the gauge,if necessary, on a board or desk, not shown.

The setting indicator 6!! is secured by any suit of permitting anaccurate sight reading of the graduations 62 relative to the pointer 56.A setting and adjusting device is secured to the indicator 60' having agear 68 and a knob 69 so that upon rotation of the knob 69 theinstrument 51 may be set to any desired reading of the scale 62 relativeto the pointer 68, the gear 68 meshing with the teeth 6| on the scaleportion 59.

Theindicating and recording instrument of Figs. 1 to 5 can be usedinmany difierent ways to indicate and record any desired items, values,composites, etc., such as certain parts or units of machines, equipmentand accessories. Fig. 5 illustrates the device m'ountedon a sheet ofgraph paper 1% on which the line H has been recorded as follows;

The machine 5'! is provided with the spiral rod is having four threadsto the inch but as explained in my said co-pending application the rod18 and its nut 3e are interchangeable for any the paper andboardwith thetwo guide lines 12 coinciding with one of the vertical lines 1'3 of thegraph or record sheet 19 and it is then pinned down. The instrument-51is now placed on the gauge by means of the pivot 64; The knob 69 is nowrotated and thus the instrument 51 is adjusted to bring the pointer 66in register with the s'pecific graduation 62 corresponding to theproportion to be used and the machine 5'! is then pinneddown by the pins2| on the board or other support. In the setting shown, Fig. 5', thepointer 66 is in register with a four graduation. The spiral rod i8makes fourturns-to one inch travel 5 the inner ring, Fig. 6, indicatethe longitudinal The outer ring 78 is" provided with proportional linesor marks 93 of the nut 35 and therefore upon each impulse of theelectromagnet l9 or 20 the rod is given a quarter turn resulting in aone-sixteenth inch travel of the nut 36 and the arm 38.

The machine is thus set for a four to one proportion which means thatthe recorder or stylus 40 travels on a diagonal one unit up on the graphpaper for every four impulses. Assuming that the squares indicated bythe lines 13 and 14 are one-half inch squares, the line H which has beenrecorded indicates sixty-six items and thus the counter 45 showssixty-six. 'The graph paper is read by taking thirty-two units to eachone-half inch vertical at the proportion set. The impulses are impartedinto the machine by means of suitable control elements as for instanceshown in my co-pending application, Serial No. 420,727, filed November27-, 1941. I

The pointers 25 and 26 may be used under any circumstances to indicateany desired limits since such pointers are operated by the actuating pin39 of the arm 38. Also the tapes 28' and 29- may be setto any adjustedposition so that the respective contact strip 34 and 35' will close thecircuit to its respective indicating light 55 and- 58 to give a warninglight when a limit or objective has been reached.

In the form. of the instrument of Figs. 6 to 9' the machine i5 isexactly the same as the ma'-' chine 5! of Figs. 1 to 5 except that thebase plate screwed down tight the washer will be frictionally heldagainstboth rings to maintain them in adjusted position. Aplurality ,of.pins 84 similar to pins 2! are secured to thering 18 to securely fastenthe ring on a record sheet and board. I

The inner ring 17 also has a cut-out portion 85, Fig. 8, approximatelycorresponding to the cut-out portion 79 in the outer ring, thereby pro-.

viding an interfit for the two rings with the two adjacent edges 86,Fig. '7, in contact with each other. A setting or adjusting device isshown in Fig. 9 consisting of a knurled knob 81 connected by a stem 88to a gear 39, the latter meshing with the circular gear rack 80. Aspring 90 tends to urge the knob and gear 89 in the raised position,shown in dotted lines in Fig. 9, so that the gears will be out of mesh.

The indicating and recording machine 15' is" secured to the inner ring Hby means of screws SI and arrow graduation lines or marks 92 on axis ofthe machine 15.

corresponding to certain proportions to which the machine may be setrelative to the graph lines .94 and 95 of the record or graph sheet 96.Another set of arrow graduation lines or marks 9! are provided on theouter ring 18 at diametrically opposite points. 7

The machine of Figs; 6 to 9 may be operated as follows, as explained inthe setting of Fig. 6 and the line 98 recorded on the sheet 96, it beingunderstood that the machine may be operated electrically as describedand shown. in" my said co-pending applications. i i

The machine I and I6 is placed on the record sheet 96 and the ring I8 islined up relative to the lines 94 and 95 on the record sheet by means ofthe arrow marks 91. With the Winged nut ,82 loose the inner ring 11 withthe machine I5 is rotated to the proportion desired, as shown forinstance, two and one-half to one, in which case mark 99 is lined upwith the arrow mark 92 on the inner ring by means of the gear 89 andrack 89 by pressing down on the knurled knob 81. When adjusted as shownin Fig. 6, the winged nut 82 is tightened and the machine is ready toreceive the impulses which will record the line 98 and operate thecounter 45.

As shown on the edge I99 of the record sheet each horizontal line 95read vertically equals twenty items so that the line 98 indicates fiftyitems drawn as a result of fifty impulses and fifty is registered in thecounter 45, the line 98 having been started at the zero line. A

In the apparatus according to Figs. to 11, the instrument 51 comprisesthe elements and details as disclosed in, Figs. 1 to 6. The modifiedstructure is shown as mounted on a board or table I9I having marginalstrips or slats I92 fastened by screws I93 or the like to the board. Theproportioning gauge 58 is provided as usual with'gear teeth I94 on theperipheral edge thereof and proportional graduations or mark I95. Thegauge, which is similar to the one shown in Figs. 1 to 5, has, however,an extended portion I96 with a strip or bar receiving projection I91 andfastening pins I98.

A rod I99 is pivoted at a center point by means of a screw H9 at thecenter of the arc described by the gear teeth I94 and this rod has anenlarged portion III provided with a cut-out portion H2 and a pointerH3. The enlarged portion I II is also provided with an upstanding collarH4, Fig. 10a, forming a bearing for a setting or adjusting device H5, ofwhich the latter has an' actuating knob I I6 and a gear I II. This gearI II meshes with the gear teeth I94 and upon rotation of the knob H6 theangular relationship of the rod I99 may be adjusted in dependence uponthe desired proportion as indicated by the pointer H3 and thegraduations I95. The end of the rod I09 is provided with a fastening pinH8 and this pin together with pins I98 will securely place theinstrument on theboard I9I relative to the record or graph sheet I I9.

The instrument according to Figs. 10 to 11 may be operated in exactlythe same manner as those of Figs. 1 to 9 but the advantage of themachine of Figs. 10 to 11 is that with one setting of the proportionalgauge it is merely necessary to slide the instrument 51 on the rod I99when a great many items are to be recorded without disturbing theproportional setting of the gauge. As shown in Fig. 10 the instrument5'! is pinned down on the board by the pins 2|, the proportioning gauge58 being set at four to one. The line I29 recorded on the sheet H9indicates fifty-six items and this number shows in the counter 45, Whenthe arm 38 and the stylus 49 have reached the upper end of theinstrument 51, the pins 2I are pulled to release them from the board andthe instrument 51 is moved by sliding action on the rod I99 to theright, Fig. 10, a suitable distance, after which the pins 2| are pushedagain into the board and the arm 38 and stylus 49 is run back to theupper end of the line I29.

With this machine it is of course possible to The instruments 511 and1'5 of Figs. 1 to 10 Show a stylus 49 which is stationary relative tothe arm 38. If now it would be desired to indicate certain timeintervals on the lines recorded on the record sheets, some line or markwould have to be applied manually. If it is desired to indicate andcompare items hourly, daily, weekly, or any other time interval, it isnecessary to automatically record a mark or other identifying characteron the graph paper. Fig. 17 shows a portion of a record sheet I2I with aline I22 indicating a certain number of items and small marks I23indicating time intervals. It is essential that the marks I23 beautomatically recorded by the recording stylus and Figs. 12 to 16illustrate'an electromagnetically operated device for this purpose. Asshown in Fig. 14 a solenoid I24 is secured on the underside of therecording arm or plate I28 and the core rod I25 of the solenoid isextended through a supporting plate I26 and is connected to a slidemember I2'I. This slide member I2I is secured on the under side of theplate I28 and it carries the stylus or line drawing element I29. Aspring I39 on the rod I25 moves the slide plate I21 and stylus I29 backto the is supported on an insulating bar I36 and a wire connects thestrip with a binding post I31. Upon closing a circuit I38, Fig. 12, thesolenoidis energized to operate the marking device.

The various parts of the machine may be made of any suitable materialsand proportioning gauges as well as the base plate I5 may be made ofmetal or a transparent plastic material so that the lines on the recordsheet will be visible. The

proportioning gauges may be made of clear Lucite which is a hardmaterial capable of being machined and ground to precise dimensions.

It is also obvious that the limit pointers 25 and 26 may be used toindicate the range of movement of the recording marker within a certainspecified time limit. If the limit pointers are not to be used, it ismerely necessary to move them to the end limits of the track 22 orremove them entirely,

Obviously, the present invention is not restricted to the particularembodiments herein shown and described. Moreover, it is notindispensable that all the features of this invention be usedconjointly, since they may be employed advantageously in variouscombinations and subcombinations.

I claim as my invention:

A recording device comprising an instrument for indicating and recordingitems, a rod on which the instrument is slidably mounted, a gaugeoperatively connected to the rod and having a peripheral gear rack andproportional indicia indicated thereon, and a setting device on the rodcooperating with the gear rack to adjust the instrument relative to thegauge.
